Detail DPDQ402000 - Carel Duct Mounting CO2 Sensor

Sensor Controller

DPDQ402000 - Carel Duct mounting CO2 sensor with a 0 to 10 Vdc output

Alat pengukur CO2 dan campuran gas yang dikendalikan mikroprosesor yang dapat dikalibrasi sendiri digunakan untuk mendeteksi kualitas udara dan ⁄ atau kandungan CO2 di udara dalam kisaran 0 ppm hingga 2000 ppm CO2. Mengukur sinyal diubah menjadi sinyal standar 0 -10V. Kandungan CO2 udara ditentukan oleh sensor NDIR. Kalibrasi sendiri dari pengukuran CO2 berlangsung dalam siklus ca. 7 hari. Untuk memastikan fungsi ini, perangkat perlu diberi udara segar (kandungan CO2 300 ... 400 ppm) setidaknya sekali setiap 7 hari. Rentang deteksi kualitas udara dikalibrasi untuk aplikasi standar seperti pemantauan di ruang perumahan dan konferensi. Masa pakai sensor gas campuran yang digunakan untuk tujuan ini terbatas. Itu tergantung pada jenis dan konsentrasi gas pencemar. Ketika parameter khusus perangkat diamati, masa pakai yang diharapkan setidaknya 36 bulan.
